Subject: RE: EVOP - Any experience/Mullins/Brauer
Sheila Mullins asks -- Does anyone have any information on a course called "Evolutionary Operation of Processes (EVOP)" which is referenced in QS-9000, section II.2- Continuous Improvement?
Reply -------------------------
While I cannot recommend a "course", you will find information on EVOP in statistics books on experimental designs. Look for one that has Response Surface Methodology in it. Here's a brief description of EVOP from one such book --
EVOP consists of systematically introducing small changes in the levels of operating variables, usually 2^k factorial designs, such that serious disturbances in yield, quality or quantity will not occur, yet large enough that potential improvements will eventually be discovered.
-- Design and Analysis of Experiments, 3rd Edition
-- by D.C. Montgomery, 1991, John Wiley & Sons, Inc.
-- ISBN 0-471-52000-4
Also, you should note that in QS 3rd Edition, Continuous Improvement is now 4.2.5 and EVOP was deleted from the examples list. However, I believe it would still be acceptable to use EVOP since it is a type of DOE (Design of Experiments) which remains on the examples list.
NOTE: Introduced in the 1950s by George Box, EVOP is an ongoing mode of using an operating full-scale process, so that information on how to improve the process is generated from a simple experimental design while production is underway. To avoid appreciable changes in the characteristics of the product, only small changes are made in the levels of the process variables. EVOP is designed to be run by process operators on a full-scale manufacturing process while it continues to produce satisfactory products.
EVOP is a tool in which a continuous investigative routine becomes the basic mode of operation for the plant and replaces normal static operation.
Hope this helps.
